AAKTds oop, semi-good flop

[mrmr]

$5/10 PLO 6-max. Villain has been potting it preflop nearly every hand for a couple of rounds. Post-flop, I have not seen him c/r, and when he has gone to showdown, his hands have been fairly random (bad) starting hands that connected with one or two pair on the flop. All bets have been pot sized, before and after the flop.

The rest of the table have loosened up with a lot of limp/calls preflop, but so far no limp/raises.

SB (500)
BB (500)
Hero (1100)
Villain (2000)
LP (2000)
BTN (1000)

Hero dealt AxAyKxTy
Hero limps, Villain raises pot ($45 total), LP calls, BTN calls, SB calls, BB folds, Hero raises pot ($280 total), Villain calls, everyone else folds.

Flop: Tx 8y 2x (pot size $705)

Any thoughts on how to proceed? Or comments on the preflop play? Thanks.
